In the recent past there have been significant research and industrial efforts to support access to large amount of geospatial data sources. Examples of industrial efforts include different data access standards proposed by the Open Geospatial Consortium (OpenGIS)1 and the availability of satellite imagery and other data on websites, such as TerraServer2. In order to better understand the resea...

In the Digital Forestry area, there is more and more requirements for spatial information connection and processing. From a prototype of geospatial computational grid (GCG), the relationship between the geospatial computational grid and OGC Interoperability protocols is proposed in this paper. A prototype of geospatial information grid is given in this paper. Digital Forestry Grid is proposed a...

With the increasing abundance of technologies and smart devices, equipped with a multitude of sensors for sensing the environment around them, information creation and consumption has now become effortless. This, in particular, is the case for photographs with vast amounts being created and shared every day. For example, at the time of this writing, Instagram users upload 70 million photographs...

Qualitative spatial reasoning is an important function of the human brain. Artificial systems that can perform such reasoning have many applications such as Geographic Information Systems (GIS), robotics, biomedicine, and engineering. Automation of such analytical processes alleviates manual labor, and may increase the accuracy of the spatial assessments because the reasoning can be done object...

This paper considers a new kind of knowledge discovery among spatial objects|namely that of partial boundary shape matching. Our focus is on mining spatial data, whereby many objects called features (represented as polygons) are compared with one or more point sets called clusters. The research described has practical application in such domains as Geographic Information Systems, in which a clu...

This article examines park use in relation to neighborhood social (safety and poverty) and urban form (pedestrian infrastructure and street network pattern) characteristics among youth and adult subpopulations defined by age and gender. We utilized System for Observing Play and Recreation in Communities (SOPARC) and Geographic Information Systems to objectively measure park use and park and nei...

While participatory design in IS has found increasing acceptance, the role of participation in social arena has been lively debated in recent years. Development projects in the third world based on “western” assumptions have elicited sharp critiques, with consequent policy shift towards involving the poor people and local communities in these endeavours. In India, policies and programs aimed at...

This paper presents a study on the modeling of fuzzy topological relations between uncertain objects in Geographic Information Systems (GIS). Based on the recently developed concept of computational fuzzy topological space, topological relations between simple fuzzy spatial objects are modeled. The fuzzy spatial objects here cover simple fuzzy region, simple fuzzy line segment and fuzzy point. ...
